8353. Roscoe, J. H., and Smyth, J. C. June 5. Two-stroke-cycle engines.-In an engine having a pump space in the interior of a hollow piston 11 which slides over a fixed head 5, admission to the pump space is controlled by a series of ports 9 in the wall of the piston. Charges enter the pump space through a non-return valve 7 and after compression are conveyed to the combustion space through the passage 16 and a valve 4. Terminal inlet ports which are overrun by the piston may be used.
